I need some help changing a .stl model

[MattSal]

I also reduced the vertex/triangle count on the model from 1.8 million to just over 28K which will improve response in any program that loads the model. Even though Fusion 360 is free for the hobbyist, it's challenging to know the precise commands or keywords for which to search to accomplish a specific task. I used Meshmixer and a bit of a hack/work-around to remove the text. I learned something in the process for future utility.

Thank you so much. I am pretty new with 3d printing. I downloaded meshmixer but didn't quite know what I was doing.
Thanks again

Thank You again fred_dot_u

For you specific tour of the steps taken to remove lettering, I downloaded the newest MeshMixer installer it over my older version.
Now will search for tutorials to start learning how to make MeshMixer work for me...
